Got this while sick of waiting 8+ months for an NHS fitting. Was a good interim option, but luckily 10 days after arrival finally got my NHS appointment. Used for 5 to 10 hours max. Ideal if you are deaf in one ear like me as this single model is intended for such people. Fits either ear. Makes conversation, meeting, TV, etc much easier. Simple on and off, volume control and charging. All original items included as new. 'The Britzgo Digital Hearing Amplifier is a sleek black in-ear sound amplifier designed for unisex adults.
